The purpose of the article is developing approaches to the forming of medioprudential supervision system, picking out homogeneous structural and functional groups of banks as the objects for supervision, elaborated criterion basis for the picking up groups of banks, formalized their identifiable characteristics, suggested approaches to the early diagnostics of the banks financial stability loss threats, supervision activities differentiation according to the specification of the groups of banks. The subject of this study is toolkit reform of banking supervision in Ukraine using structural and functional analysis.
